THOMAS DAVISAND WILLIAM W. TYLER, OF CLEVELAND, OHIO; SAID TYLERASSIGNOR TO SAID DAVIS.

FEED-WATER HEATER AND PURIFIER.

SPECIFICATION' forming part of Letters Patent No. 345,578, dated July13,1886.

Application filed March 13, 1886. Serial No. 195,123. (No model.)

.To all whom, it may concern.-

Beit known that we, TIIoMAs Davis and WILLIAM NV. TYLER, of Cleveland,in the county of Cuyahoga and State of Ohio, have invented certain newand useful Improvements in Combined Feed-Water Heaters and Puriers; andwe do hereby declare,the following to be a full, clear, and exactdescription of the invention, such as will enable others skilledin theart to which it pertains to make and use the same.

Our invention relates to improvements in combined feed-water heaters andpurifiers; and it consists in certain features of construction, and incombination of parts hereinafter described, and pointed ont in theclaims.

III the accompanying drawings, Figure l is an elevationin section of adevice embodying ourinvention. Fig. 2is a horizontal'section on the lineof x m, Fig. l. Fig. 3 is an elevation showing in detail a section ofthe depending perforated pipes.

A represents a container, that is preferably cylindrical and upright,and having a concaved bottom, A', supported on legs a, and a crowning`detachable cover, A2.

Internal ilanges A3 support the respective disks B, O, D, E, and F, thatpartition the container off into the several compartments.

The pipe c', provided with suitable valve for blowing off sediment fromthe deposit-chamber, is connected with the head A', and the inductionfeed-water pipe c is connected with the head A2.

Gr is a hollow ball, connected in the pipe o2 near the container A, andhas suspended inside a second hollow globe, H, that is connected with asteam-pipe, H'. A small nozzle, h, discharges from the ball Hinto thepipe a2 in the direction shown by the arrow. The feedf water,in passingthrough the globeG and sur O, and extends to near the bottom of thecham-1 ber C'. The overflow of the chamber O' is through the pipe d,that extends through the discharging-chamber D', and through theltering-chamber, and to near the bottom of the deposit-chamber.

Pipes I, for the passage of live steam, lead, respectively, into the topof theehambers B' and O'. These chambers are each provided with aseriesof perforated plates, J, that rest in grooves inthe respective bottomsGand D, and extend to near the top of the respective chambers. Dependingperforated pipes i lead from the pipes I down between the plates J, withthe perforations arranged to discharge lengthwise of the plates J.

It will be observed that the inlet and outlet pipes of the respectivechambers Bl and C are located on opposite sides of the respectivechambers, so that the. water in passing from the inlet-pipe to theoutlet-pipe must pass through the series of perforated plates, and inthe narrow spaces between these plates encounter jets of live steam fromthe pipes z. Theresult is that the feed-wateI-,when it leaves thechamber C', is usually at the boiling-point, so that when the waterpasses through the piped into the deposit-chamber the most of theimpurities in the water, especially those of a mineral character, areprecipitated, and such of a vegetable nature as are not precipitated arearrested as the water passes up through the filtering-chamber. Theplates E and F are both perforated, and this latter chamber may beiltered with any of the well-known materials suitable for this purpose.

The heated and puriiied water is discharged into the chamber D', fromwhence it passes through the pipe K to the boiler.

What We claim is- 1. In a feed-water heater and purifier, thecombination, with an induction feed-water pipe, and a sphericalcontainer connected in the said pipe, of a second spherical container1ocated inside the first, the second container having attached a pipefor supplying live steam, and having a discharging-outlet presenting inthe same direction as the water iiows through the said induction-pipe,the parts being arranged substantially as set forth.

2. In a feed-water heater and purifier, the

ICC

inlet and outlet, of perforated steam-pipes arranged between the saidpartitionplates, the

parts being arranged substantially as set forth. I 5

[n testimony whereof we sign this specifica tion, in the presence of twowitnesses, this 25th day of January, 1886.
